What are the requirements of the mold making factory?

What are the general requirements for mold making? The editor of the insert mold factory tells you:

First, work closely with the mold maker

(1) It can ensure that the planned product has a good forming process, and the shaping plan will not be modified because the parts are difficult to process.

(2) The mold making party can make planning preparations in advance to prevent poor consideration in a hurry and affect the construction period.

In short, to produce high-quality molds, only close cooperation between the supply and demand sides can reduce costs and shorten the cycle.

Second, don't just look at the price, but consider all aspects from quality, cycle and service.

There are many types of molds, which can be roughly divided into ten categories. According to different requirements of parts materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, economy, etc., different types of molds are selected.

Moulds with high accuracy requirements need to be processed with high-precision CNC machine tools, and mold raw materials and forming processes have strict requirements. CAD / CAE / CAM mould skills need to be planned and analyzed. Because some parts have special requirements during molding, the mold also needs to use hot runner and gas-assisted molding. Production manufacturers should have CNC, EDM, wire cutting machine tools and CNC copy milling equipment, high-precision grinding machines, high-precision three-coordinate measuring instruments, computer planning and related software. In general, large-scale stamping dies (such as car cover molds) should consider whether the machine tool has a blank holder mechanism, or even a side lubricant, and multi-function progressive. In addition to punching tonnage, punching times, feeding devices, machine tools and die protection devices must be considered.

Not all enterprises possess and master the manufacturing methods and processes of the above molds. When selecting a partner manufacturer, we must understand its processing capabilities, not only looking at the hardware and equipment, but also combining management levels, processing experience and skills. For the same set of molds, there are sometimes large gaps between different manufacturers' quotations. You should not pay more than the cost of the mold, nor should it be less than the cost of the mold. The mold maker, like you, must get a reasonable profit in the business. Customizing a set of molds with much lower quotes can be a laborious start. Users must start from their own requirements and make a comprehensive measurement. A much lower mold would be the start of trouble. Users must start from their own requirements and make a comprehensive measurement.

Third, prevent multi-head cooperation, as far as possible one-stop mold making and product processing.

With qualified molds (qualified specimens), divergence can produce qualified products in batches. This is mainly related to the selection of the machine tool for the part, the forming process (forming temperature, forming time, etc.) and the skill of the operator. With a good mold, but also a good forming process, one-stop cooperation is better, try to prevent long-term cooperation. If the conditions are not met, it is necessary to select one party to take full responsibility, and it must be made clear when the contract is concluded.
